### Section 5 - Hypertext

Back in Section 1, we started out by looking at the layered network architecture used in the Internet. Using a World Wide Web transfer as an example, I outlined how an Internet operation occurs. Then we started looking at some of the protocols involved in more detail. The Domain Name Service (DNS) converts a hostname into the IP address needed by the lower layers. The TCP protocol opens a connection to a port on the host, using the IP protocol to actually transfer the packets. All that's left is to examine what actually gets transfered over the TCP connection.

In this section, we'll conclude this example by examining the various protocols and standards that define the data portion of the TCP exchange.
